Medical Xpress / Two experimental malaria vaccines show promise, with one slowing replication of active parasites in the bloodstream
Two experimental malaria vaccines are not only safe for humans, one of those immunizations prompted a slowing of the malaria parasite's replication in the bloodstream of clinical trial participants, scientists have found ...
Medical Xpress / Spatial positioning of enzyme helps natural killer cells distinguish healthy cells from diseased ones marked for death
Questions abound when it comes to the molecular mechanisms deployed by the human immune system to thwart cancer and infection, and questions especially abound when it comes to the precise steps taken by the innate immune ...
Medical Xpress / Experimental monoclonal antibodies can coax aggressive prostate and breast cancers into submission, finds research
Therapeutic antibodies that cause aggressive tumors to become susceptible to treatment are being studied with the hope of one day changing the fate of patients who either relapse soon after cancer therapy or whose stubborn ...
Medical Xpress / Global team of scientists discovers why herpes simplex encephalitis is so devastating in some babies and children
Defects in a single protein involved in cell death may impair the immune system's ability to combat a herpes viral infection in the central nervous system, scientists have found in new research that examines a pediatric infection ...
Medical Xpress / Sleep deprivation is a risk factor for Alzheimer's, say scientists who turned to animal models to find out why
Scientists have long explored the link between disturbances in sleep patterns and neurodegenerative diseases. Powerful evidence has emerged in recent years linking disrupted sleep to Parkinson's, and a massive body of research ...
Medical Xpress / The hunt is on for the telltale biomarker revealing precise degree of protection conferred by Moderna's mRNA vaccine
A new analysis is shedding light on antibody measurements that can help predict the protective capabilities of the Moderna mRNA vaccine for COVID-19.
Medical Xpress / Whether causing the common cold or COVID-19, coronaviruses deploy key enzymes to elude human immune response
The entire family of coronaviruses is equipped with multiple methods of evading the human immune system, and two new studies have taken a deep dive into how these viruses, including SARS-CoV-2, leverage highly specialized ...
Medical Xpress / Tiny protein apparently produces titanic impact in the lungs when encountering bacterial pneumonia
In the ongoing quest to discover which constituents of the immune system provide highly specified protection, scientists have found that a component of the innate immune system is endowed with the capability of guarding the ...
Medical Xpress / Killing is their job: Two studies analyze natural killer cells as they tackle the worst form of malaria
Scientists are unraveling the complex mystery underlying how the immune system mounts a potent defense against one of the world's most relentless killers—the deadly parasites that cause the worst form of malaria.
Medical Xpress / Tumor-infiltrating T cells may be markers to predict patients' responses to cancer immunotherapy
New insights into a population of tumor-infiltrating T cells may ultimately allow doctors to predict how patients will respond to checkpoint blockade immunotherapy, a form of cancer treatment with advantages that doctors ...
Medical Xpress / An antibody-based drug triggers rare inflammatory eye problems in macular degeneration patients
A drug approved in 2019 for macular degeneration apparently caused rare retinal side effects because of its interactions with the human immune system, two new studies have concluded.
Medical Xpress / Scientists shed new light on two proteins that exacerbate the progression of Parkinson's disease
Two proteins may be intimately linked to the progression of Parkinson's disease, a relentless and disabling neurodegenerative disorder that affects millions of people around the world.
Medical Xpress / Study: Experimental COVID shot made via egg-based technology elicits higher antibody proportion than mRNA vax
An experimental COVID-19 vaccine produced with technology based on a decades-old method, elicited virus-neutralizing antibodies in higher proportion than the amount induced by mRNA immunizations, a Phase 1 clinical trial ...
Medical Xpress / Human feces and urine contain a motherlode of health data: 'Smart toilets' detect daily fluctuations, serious disease
A disease-detecting toilet capable of a range of monitoring and surveillance activities could soon be reality, and while the device may test for everything from how fast your urine flows to reporting on your vital signs, ...
Phys.org / Scientists decipher how non-resistant forms of Staph aureus thwart antibiotics, almost like a superbug
Staphylococcus aureus (S. aureus) has a slew of surprises in its bag of dirty tricks and among the most puzzling has been the ability of non-resistant forms of the bacteria to emerge unscathed, even after exposure to high ...
